Interesting development here. I had up until now not checked into United. I decided to do a trial run on Tuesday and see how quickly the points would show up. Today I check my United account and see 200 miles in my account from TopGuest. 50 on Tuesday, but then 50 on Wednesday, Thursday and Friday. I didn't check into United on those days. Wonder what gives. I am very careful with my check ins and do not want to alert the Cardinals. This worries me a bit. Has anyone else had this occur?
